10. The Battle of Santiago
This 1962 World Cup match is considered one of the most brutal games in World Cup history, and it was provoked by a couple of Italian journalists who decided it was their job to poke fun on the country hosting the tournament, which had just suffered a massive earthquake. In the end those journalists had to be quickly taken outside of the country for their own safety.
Ironically enough, Ken Aston, the referee who “pretended” to referee this match was the same person that would go on to introduce the usage of yellow and red cards.
